Protection degrees IPXXB and IPXXD are related respectively, to the contact of a jointed test finger and a test wire with hazardous parts (Annex 3).
If necessary a mirror or a fiberscope may be used in order to inspect whether the Jointed Test Finger touches the high voltage buses.
If this requirement is verified by a signal circuit between the jointed test finger and high voltage live parts, the lamp shall not light.
The jointed test finger described in the figure of the appendix to this annex shall be inserted into any gaps or openings of the physical protection with a test force of 10 N ± 10 per cent for electrical safety assessment.
Contact safety test with test finger with a diameter of 12.5 mm
Starting from the straight position, both joints of the test finger shall be successively bent through an angle of up to 90 degrees with respect to the axis of the adjoining section of the finger and shall be placed in every possible position.
Starting from the straight position, both joints of the test finger shall be successively bent through an angle of up to 90o with respect to the axis of the adjoining section of the finger and shall be placed in every possible position.
Starting from the straight position, both joints of the test finger shall be rotated progressively through an angle of up to 90° with respect to the axis of the adjoining section of the finger and shall be placed in every possible position.
This International Standard need not be applied to machinery which is covered by certain electrical standards in which specific testing procedures are laid down, for example using the test finger.
